Sierra 4345 Tipped GameKing 6.5mm 145gr Hunting Bullets 100/Box

The Sierra 4345 Tipped GameKing delivers exceptional accuracy and terminal performance for 6.5mm rifle cartridges. This 145-grain hunting bullet combines Sierra's proven GameKing design with a polymer tip for improved ballistic coefficient and reliable expansion on medium to large game.

What Makes This Different

The polymer tip design reduces drag and initiates consistent expansion at impact velocities as low as 1,800 fps. Unlike traditional soft-point bullets that can deform during feeding, the streamlined tip maintains bullet integrity in magazine-fed rifles. The boat-tail base reduces drag by approximately 6-8% compared to flat-base designs, extending effective range and improving wind resistance.

Key Features

• 145-grain weight optimized for 6.5mm Creedmoor, 6.5x55 Swedish, and similar cartridges
• Polymer tip initiates expansion while improving ballistic coefficient to 0.550
• Boat-tail design reduces drag and improves long-range trajectory
• Tapered jacket construction controls expansion from muzzle to 400+ yards
• Spitzer profile feeds reliably in bolt-action and semi-automatic rifles
• Sectional density of 0.297 provides deep penetration on large game
• Match-grade construction maintains sub-MOA accuracy potential

Field testing demonstrates consistent 1.5-2x bullet diameter expansion at impact velocities between 1,800-2,800 fps. The controlled expansion design retains 65-75% of original weight while creating effective wound channels on deer, elk, and similar-sized game. Temperature stability remains consistent from -20°F to 125°F, making these bullets suitable for various hunting conditions and climates.
